TAKE-UP FOR TRIMMING-LOOMS.

Specicaton of Letters Patent No. 25,538, dated September 20, 1859. r

To all whom 'it may concern:

Be it known that I, SAMUEL WALKER, of Roxbury, in the county of Norfolk and State of Massachusetts, have invented an Ilnproved Take-Up for Trimming-Looms, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which is shown a view of the front part of a loom with my improved takeup attached.

In looms for weaving trimming and other narrow goods, the ordinary take up is found to be inconvenient, as the narrow stuff heaps up on the roll in an irregular manner and cannot be circulated or wound evenly over the length of the roll by means of a guide, on account of the soft and yielding nature of the edges of the s'tulf. To overcome this ditliculty is the object of my present invention which consists in giving to the take up roll used in such looms a reciprocating motion back and forth lengthwise on 4its axis at the same time that it is rotated.

That others skilled in the art may understand and use my invention I will proceed to describe the manner in which I have carried it out.

In the drawings A represents the end frame of a loom, to each end of which are attached brackets a which serve as bearings for a shaft B; this shaft is made square for its whole length between its bearings, and carries a roll C fitted with heads e, so that it may slide freely along the shaft at the same time that it is rotated as the shaft revolves. A cog wheel D on one end of this shaft engages with a pinion b on a short shaft c which has its bearing in a bracket cl, attached to the frame A; this shaft o, has alsov attached to it a ratchet wheel E. A lever F the outer end of which is connected with some reciprocating part of the loom, is pivoted on the shaft c, and has pivoted to it a dog f, which engages with 'the ratchet wheel E, and is held up to it by a spring g (shown dotted). A retaining pawl 71., is pivoted at 3, to the side ofthe frame A. As the lever F, is 'vibrated the ratchet wheel E, is revolved in the direction of its arrow, and the wheel D in the direction of its arrow carrying the roll C, with it.

Thus far the movement is similar to the ordinary take up.7 The shaft B at its opposite end carries a pinion Gr which engages with a cog wheel H, supported on a bracket 7c projecting from the frame A. To a pin z' projecting from the face of the wheel H is pivoted a rod I which is connected at its other end to a bell crank K which is pivoted at et, to the frame A. The rod I is connected to the crank K, in the following manner. The rod I, enters a slot in the block Z, and is pivoted to it at 5, and the block Z, is pivoted to one of the arms of the crank K. To the other arm of the crank K, is pivoted a rod L, which is connected at its other end by a pin m, with a horizontal bar M, which slides longitudinally in its bearings in the brackets n, which project from the frame A, one at each end. From the bar M, rises a standard N, the upper end of which is formed into a fork which enters a groove 0, in one of the heads e, of the roll C. As the roll C is revolved as before stated each revolution of the wheel II, rocks the crank K, and slides the bar M, back and forth in its bearings, this slides the roll C longitudinally on the shaft B at the same time that it is revolved, and the goods being wound up on the roll are laid on in regular layers as desired.

For the convenience of removing the goods from the roll, the ordinary sheet metal sleeve or nerow P, is slipped onto the roll and is clutched to it by notches 1 and a pin s. The strip of goods R as it comes from the loom is wound onto the nerow which when full may be slipped back from the pin s. and the goods unwound. Any number of these nerows may be placed upon the roll C.

I do not claim the mechanism herein described irrespective of its application to and connection with looms for weaving narrow fabrics as described, but

lhat Ido claim and desire to secure by Letters Patent is- Giving to the take up roll of a trimming loom a reciprocating motion longitudinally on its axis for the purpose specified.

SAMUEL WALKER.
